The Impact Of Cluster Strength On Wages: An Empirical Analysis, Devan Schaefer Jan 2023

The Impact Of Cluster Strength On Wages: An Empirical Analysis, Devan Schaefer

Electronic Theses and Dissertations

In this thesis, I examine the relationship between clusters (i.e., the grouping of competitive, interconnected industries within a geographical area) and wages, building upon the work of Marshall (1890) and Porter (2003) on the importance of clusters for regional economic development. I seek to answer two research questions. First, after accounting for robustness tests, do clusters continue to affect wages positively? Second, is labor force productivity the only channel through which this relationship occurs? In my analysis, I employ ordinary least squares, two-stage least squares, and fixed effects regression analyses using panel data from 2009 to 2014 for every U.S. …

The Live Bait Trade As A Pathway Of Inland Invasive Fish Species Introductions, Hannah Mulligan Jan 2023

The Live Bait Trade As A Pathway Of Inland Invasive Fish Species Introductions, Hannah Mulligan

Electronic Theses and Dissertations

Freshwater systems are susceptible to numerous anthropogenic pathways of invasive species introductions and subsequent establishment. Once establishment occurs, invasive species not only impact biodiversity, ecosystem function, and human health, but also cost the global economy billions of dollars every year. Recreational fishing is one of the most prevalent pathways for invasive species introductions in freshwater systems due to increased propagule pressure from boating and angling activity. Within recreational fishing, the live bait trade represents a secondary pathway whereby anglers illegally release baitfish (and water) that may contain invasive species. Preventative actions, including regulations, education, and inspections have been implemented to …

Unveiling Race Diversity And Fungicide Sensitivity Profiles Of Pyrenophora Tritici Repentis Populations In South Dakota Collected From 2021-2023, Jaswinder Kaur

Electronic Theses and Dissertations

Tan spot, a foliar disease of wheat caused by the ascomycetes fungus Pyrenophora tritici repentis (Ptr), poses a significant threat to wheat crops globally. The disease gained economic importance in the late 1970s due to shifts in farming practices, such as minimal tillage and planting on crop residues, providing favorable conditions for the pathogen to overwinter and cause infections. Ptr is classified into eight races based on the production of necrotrophic effectors—Ptr ToxA (necrosis-inducing), Ptr ToxB, and Ptr ToxC (chlorosis-inducing on respective susceptible and sensitive cultivars)—resulting in distinct symptoms on susceptible wheat differentials. The inverse gene-for-gene hypothesis of Ptr suggests …

Electrochemical Innovations: Advancements In Lithium Metal Batteries & Supercapacitor For Energy Storage, Jyotshna Pokharel

Electronic Theses and Dissertations

Constructing an artificial solid electrolyte interphase (SEI) on lithium metal electrode is a promising approach to address the rampant growth of dangerous lithium morphologies (dendritic and dead Li0) and low Coulombic efficiency that plague development of lithium metal batteries. But it is not known how the Li+ transfer behavior in the SEI is coupled with mechanical properties. We demonstrate here a facile and scalable solution-processed approach to form a Li3N-rich SEI with a phase-pure crystalline structure that minimizes the diffusion energy barrier of Li+ across the SEI. Compared with a polycrystalline Li3N SEI obtained from conventional approaches, our phase-pure/single crystalline …

Fungicide Sensitivity In P. Tritici-Repentis Diverse Population And Phenotyping Of Spelt Wheat For Multiple Diseases, Zunera Shabbir

Electronic Theses and Dissertations

Pyraclostrobin, a QoI fungicide, is extensively used in the management of fungal leaf spot diseases. In this study, 215 P. tritici-repentis isolates collected from wheat fields in South Dakota were evaluated for their sensitivity to Pyraclostrobin. Of 215 isolates, 48 isolates (22%) exhibited insensitivity based on G143A mutation and EC50 values using spore germination assay. Our results indicate reduced sensitivity to insensitivity to pyraclostrobin in some isolates suggesting regular monitoring of the P. tritici-repentis population to QoI fungicides is essential to track the evolution of insensitive population. Spelt wheat (Triticum spelta L.) is an ancient cereal that is gaining small …
